The Wacker Neuson Seal is a genuine OEM seal designed for the LTN4Y and LTN5Y light tower series as well as the APT4S and APT4T pump series. Sourced directly from Wacker Neuson, this seal meets the original design specifications, ensuring a drop-in fit without guesswork. It covers an extensive range of configurations across both light tower and pump product families, including cold weather and specialty variants.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original material and compression standards, delivering the same fluid and pressure retention as the factory-installed seal.
- Direct Drop-In Replacement — Engineered to the exact profile and dimensions of the original, seating correctly without trimming, shimming, or additional hardware.
- Broad Series Compatibility — Fits LTN4Y and LTN5Y light tower variants — including 60 Hz, 120V/60Hz, SA, CH, UK, RH, and HD configurations — plus APT4S and APT4T pump units with surge brake, electric brake, and cold weather options.
- Prevents Fluid Loss and Contamination — A correctly functioning seal keeps fluids contained and contaminants out; a worn or cracked seal leads to leaks, pressure loss, and potential damage to surrounding components.
- Genuine Wacker Neuson Part — Part number 5200019860 is an authorized OEM component, so you can trust you're installing exactly what the machine was built with.
A seal acts as a barrier between moving or mating components, preventing the escape of fluids or gases and blocking the entry of dirt, moisture, and debris. In light towers and pump equipment, seals are critical to maintaining system pressure and protecting internal components from premature wear. When a seal degrades or fails, leaks develop quickly, performance drops, and the risk of secondary damage to pumps, bearings, or drive components increases significantly.
